Tai chi could be key to overcoming cognitive effects of chemotherapy

07.06.2011

According to the American Cancer Society, more than 11.4 million Americans are currently living with cancer. While cancer treatments are plentiful, many have negative side effects.

Previous studies have indicated that a significant number of patients who receive chemotherapy also experience cognitive declines, including decreases in verbal fluency and memory. Now, one University of Missouri health psychologist has found evidence that indicates Tai Chi, a Chinese martial art, might help overcome some of those problems.

"Scientists have known for years that Tai Chi positively impacts physical and emotional health, but this small study also uncovered evidence that it might help cognitive functioning as well," said Stephanie Reid-Arndt, assistant professor and chair of the Department of Health Psychology in the School of Health Professions. "We know this activity can help people with their quality of life in general, and with this new study, we are encouraged about how Tai Chi could also help those who have received chemotherapy. I also hope this encourages more people to think about Tai Chi positively on a broader scale in their lives."

Tai Chi involves practicing slow motion routines and is based on several principles, including mindfulness, breathing awareness, active relaxation and slow movements. The emphasis on slow movement makes Tai Chi particularly suited to a wide range of fitness levels, which makes it very relevant for those who have had chemotherapy and might be experiencing physical limitations as a result, Reid-Arndt said.

The MU pilot study followed a group of women with a history of chemotherapy. The women participated in a 60-minute Tai Chi class two times a week for 10 weeks. The women were tested on memory, language, attention, stress, mood and fatigue before and after the 10-week sessions. According to Reid-Arndt, the results of the tests indicated that the women had made significant improvements in their psychological health and cognitive abilities.

"Tai Chi really helps individuals focus their attention, and this study also demonstrates how good Tai Chi could be for anyone, whether or not they have undergone treatment for cancer," Reid-Arndt said. "Due to the small size of this study, we really need to test a larger group of individuals to gain a better understanding of the specific benefits of this activity for patients who have been treated with chemotherapy and how significant these improvements might be."

The study was published recently in Complementary Therapies in Clinical Practice.

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
